Victor Hillside Horizon

Victor Hamaker

Program Director

With a strong commitment to supporting individuals with special needs, and at risk youth, I have built a career dedicated to advocacy and behavioral health. My journey began as a Direct Support Professional (DSP) in group homes and for the local school district for both adults and adolescents with special needs, behavioral challenges, and at-risk youth. I then transitioned into behavioral health, serving as a Behavioral Health Technician (BHT) at Hillside Horizon, where I worked closely with at-risk youth and individuals with complex behavioral needs. I later advanced to Lead BHT and then Operations Manager. Currently, as the Program Director at Hillside Horizon, I oversee program development, staff training, and client care, ensuring high-quality services for individuals with behavioral and developmental challenges. Additionally, I support the local school district as a special needs advocate, working to enhance resources and support for students and families.
